At the church ceremony, Duohui (Song Hye-kyo) was so magnanimous about the accidental death of her fiance that she even forgave the 17-year-old Zhimin, who wrote a petition to plead with the judge. However, the fiance's eldest sister was so bitter about it that she even accused Duohui of not letting the murderer be punished. At parting, the eldest sister gave Duohui a birthday present. This makes Duohui fall into the memory of her dead husband: one rainy night a year ago, her fianc é drove Duohui home together, because that day was her birthday, and they were extremely happy to recall the good memories of their love affair. At this time, the fiance received a phone call from his drunken friend. Duohui thoughtfully asked him to take care of his friend first and take the bus home by himself. Unexpectedly, this parting has become a farewell. On a rainy night, my fiance was killed by Zhimin's speeding motorcycle. Duohui, who heard the bad news, always maintained patience and restraint, not only forgiving Zhimin, but also making tolerant documentaries with forgiveness and supporting church activities to abolish the death penalty. During this period, she interviewed all kinds of characters and witnessed various forms of human nature. When she learned of Zhimin's misfortune, she was shocked.
